371 6114 d 20 h jab /trunk/src/Geometry/ Ply loading was added to this Directory. Two files rply.c and rply.h which
expose an MIT licensed ply handling API have been introduced as well as
a ply_load function declared in ply_load.h and defined in ply_load.cpp		  
369 6115 d 15 h jab /trunk/src/GLGraphics/ The SOIL - simple opengl image library is in the public domain. I added it to
GEL because it is much simpler to use and more compact than DevIL.
By including it in the actual GEL distribution, we also lower the number
of external dependencies by 1 while slightly increasing compilation time.		  
368 6116 d 14 h jrf /trunk/ Bruteforce wireframe rendering introduced in draw framework and OBJViewer. Texture toggle on/off introduced in OBJViewer.  
367 6144 d 17 h jab /trunk/ Slight changes to quadric simplification. I made the interface a little saner.  
366 6144 d 21 h jab /trunk/src/CGLA/ So a variable l has now been given a default value to protect against
warnings		  
364 6222 d 10 h jrf /trunk/src/Geometry/ Corrections to have the ray tracer run properly in Visual Studio  
363 6252 d 14 h jab /trunk/ A few changes to make quadric simplification better. In particular, boundaries
are now handled well.		  
362 6257 d 7 h jab /trunk/src/ Some added documentation and also I added the tesselation routine  
359 6371 d 8 h jab /trunk/src/CGLA/ Added 3D matrix functions for transformations  
358 6371 d 8 h jab /trunk/src/CGLA/ added rotation and scaling matrices to 3d double matrices  
357 6375 d 17 h jab /trunk/ A number of changes were made to quadric simplification  
354 6390 d 16 h awk /trunk/src/  
351 6392 d 8 h jab /trunk/ some bug fixes  
350 6403 d 13 h awk /trunk/ Worked around bug in BSPTree. "intersect_fast_node" does not work with
GCC!		  
349 6403 d 14 h awk /trunk/ Misc fixed to make it compile on ubuntu 7.10  
346 6403 d 15 h awk /trunk/  
344 6416 d 15 h jab /trunk/ The power eigensolution method was slightly broken. It seems to work now.  
342 6416 d 15 h jab /trunk/src/CGLA/ The power eigensolution method was slightly broken. It seems to work now. The test program has been improved. However, it is a simple method, and only robust on small matrices but that is what CGLA is all about  
341 6460 d 21 h jab /trunk/ Added a ply viewer to OBJViewer.
other minor changes.		  
339 6479 d 20 h jab /trunk/src/GLGraphics/ Added ply view to OBJViewer  
338 6479 d 20 h jab /trunk/src/Geometry/ Added ply view to OBJViewer  
336 6481 d 15 h jab /trunk/ Ensured that the touched value is unchanged when saving
more work to do:
In many places, I change touch values, and probably all
these should be changed so that they restore the value.		  
334 6530 d 19 h jab /trunk/src/Geometry/ Slight changes to doc.  
332 6600 d 11 h jab /trunk/src/HMesh/ Added functions for subdividing (Catmull Clark topological splits - but
not averaging) and closing holes simply by turning holes into boundary
polygons.		  
331 6621 d 17 h jab /trunk/src/ Added a draw function for HMesh  
330 6636 d 15 h jab /trunk/src/Geometry/ Some changes to the KDTree  
327 6656 d 20 h jab /trunk/src/CGLA/ Removed determinant from cpp file  
325 6656 d 21 h jab /trunk/src/CGLA/ An alternative 4x4 determinant function is included and commented out.  
324 6657 d 19 h jab /trunk/src/ Some changes. Mostly a nasty precision issue has been fixed with regard
to 4x4 determinants. KDTrees have also been improved.		  
323 6663 d 12 h bj /trunk/src/CGLA/ added generic make_rot method with rotation matrix as input  
321 6665 d 8 h jab /trunk/ No log message.  
320 6672 d 19 h awk /trunk/src/CGLA/  
319 6673 d 8 h awk /trunk/src/Geometry/ Partitioned interface into public / private..
Changed all TriMesh* to const TriMesh*
Commented normal computation code in intersect in..
Fixed bug with normals (object space normals were returned, not world space)		  
318 6673 d 8 h awk /trunk/src/Geometry/ Changed hit_object to const pointer to TriMesh  
317 6675 d 11 h awk /trunk/src/CGLA/  
316 6678 d 13 h jab /trunk/src/CGLA/ Added a constructor to Vec2i that accepts a single int.  
315 6678 d 19 h jab /trunk/ Some slight changes to QEM based decimation  
314 6711 d 19 h jrf /trunk/src/Geometry/  
313 6726 d 14 h jrf /trunk/ BSPTree ray tracing now works well !
The problem was a way too large epsilon causing triangles to appear unnecessarily in several different space division boxes. Precision has now been increased and the code has been made more robust. Try it out on the bunny.		  
311 6726 d 15 h jrf /trunk/src/Geometry/
